LIQUID-DISPENSTNG PRAIUS. l

Application led December 22, 1921. Serial No. 524,151.

To all whom it may concern.'

Be it known that I. FINGAL C. ORR, a citizen of the United States,residing at Burbank, in the county of Los Angeles -and State ofCalifornia, have invented new and useful Improvements inLiquid-Dispensing Apparatus, of which the following is a speciication.

My invention relates to dispensing apparatus for liquids, and a purposeof my invention is the provision of a dispensingapparatus which isparticularly adapted, although not necessarily, of lubricating oils atgasoline and oil supply stations, and the invention consists in aplurality of tanks or compartments, each containing a diti'erentbrando1' quality of oil, and a pump movably mounted to associate its inletport with any one of the tanks or compartments to effect, when operated,the dispensing oi oil from any one of the several tanks or compartments.

It is also a purpose of my invention to provide a liquid dispensingapparatus including a pump which functions to effect drainage of theliquid content between its periods of operation, so that at eachshifting and pumping operation the new oil introduced into the pump willnot be contaminated by the oil of the other tanks.

I will describe one form of liquid dispensing apparatus embodying myinvention, and A will then point out` the novel features thereof inclaims.

In the accompanying drawings,

Figure 1 is a view showing in side elevation and partly in section oneform of liquid dispensing apparatus embodying my in- 4"vention;

Figure 2 is a fragmentary vertical -sectional view of the apparatusshown in Figure 1;

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure1;

Figure 4 is a fragmentary sectional view showing a modified form' ofpump and tank connection embodying my invention.

Referrin specifically to the drawin s, in which simi ar referencecharacters re er to similar parts, my invention, in its presentembodiment, comprises a tank designated generally T and preferably form,as shown in Figure 3, to ren er it compact and of ornamental appearance.By

means of radially arranged partitions 15, the

for the dispensingl of poly onaly tank T is divided into a partments 16,and all of )ments are provided with a common cover plate 17 formed withintake ports 18 and dispensing ports 19, through which dispensing pipes2() are extended.r Asclearly shown in Figure 1, the lower ends of thepipes 20 terminate at points spaced from the bottom of the tank T, whiletheir upper ends are threadedly fitted within a common head H bolted orotherwise secured to the cover 1'?.

As clearly shown "in Figure 2, the liquid dispensing apparatus alsoincludes a pump comprising a cylinder 21, the lower end of which isnormally closed by an 'integrally formed .head 22, movement on the headH by means of a rod 23 threadedly iitted in the head 22 and extendingloosely through the head H with its lower end extending into a sleeve24, where it is provided with a nut 25' and a washer 26, the latterbearing against a coiled expansible spring 27 for normally urging therod and, consequently, the head 22, downwardly toward the head H. Thelsleeve 24 constitutes' the axis of the tank T and provides means forrigidly sustaining the inner ends of the partitions 15 in the mannerclearly shownin Figure 3. The upper Vendof the cylinder 21 is closed byahead 28 secured to the cylinder by means of bolts 29 and formed with anaxial opening which slidably receives the rod 30 of a piston 31. The

the compartpiston 31 is mounted for sliding movement f within thecylinder 21 and movement of this piston is effected through the mediumof a.

lever 32 fulcrumed at the point indicated at 33 upon an arm 34 fixed toor formed integral with the head 28. The lever 32 is pro-4 vided a't oneend with a handle 35, while its opposite end is curved downwardly, asclear ly shown in Figure 1, and operatively connected to the upper endof the rod 30 by means of a link 36. By this arrangement, it will beseen that rocking movement of the lever 32 ett'ects areciprocating-movement of the piston 31.

As'clearly shown in Figure 2, the head H' is provided with a pluralityof ports 37, one for each pipe 20, and as there .is only one pipe foreach of the compartments4 16, 1t

will be clear that there isonly one ort 37 I v The port 3 vis in Iforeach compartment. communication with the corresponding pipe 20 at itslower end, and 1sY adapted to complurality of coml municate at its upperend with an intake port 38 -controlled by a ball valve 39, whichnormally rests onta seat 40 to close the port 38. rl.`he port38 isformed with a head 22 and at such a point therein that when the cylinder21 is rotated it will successively register'v with all of the ports 37.By this arrangement the port 38 can be moved into registration with anyone of the ports 37 by imparting a rotational movement to the cylinder21, and to visibly aindicate the exact position of the port 38 withrespect -to the orts 37, the periphery of the head H is ormed withgraduationsindicated at 41, with one graduation for each of the ports37. The head 22 carries upon its periphery a pointer or indicator 42which is adapted to co-act with the graduations 41 to visibly anddefinitely indicate the position of the vport 38, thus facilitating theregistration of such port with anydesired port 37.

As shown in Figure 2, the cludes a hollow hub portion portion 44provided axially thereof with a port 45 controlled by a ball valve 46mounted within the portion 43 to normally close such port. The hubportion 43 is formed piston 31 inwith openings 47 which work inconjunction with the port 45 to effect communication from the lower sideof the piston 31 to the upper side thereof. The oil is discharged fromthe cylinder 21l through a spout 48 threadedly iitted in the head 28 andhaving its discharge end offset with relation to the cylinder 21.

For the purpose of effecting theAv .drainage of liquid from the pumpduring the periods in which it is not in use, the head 22 is providedaxially thereof with an upstanding pin 49 which, in the lowermostposition of the piston 31 is adapted to extend 4through the port 45 soas to unseat the valve 46. stud 50 is slidably fitted within the head22. and supported upon this stud by means of an arm 51 is a lug 52tapered at its lower end and adapted to engage the ball 39 for unseatingthe latter. The stud 50 and, oonsequently, the lug 52 are urged upwardlyby means of a spring 53 so that the lug normally disengages the ball 39.However, with the piston 31 in its lowermost position, it engages anddepresses the arm 51 against the action of the spring 53, therebylofwering the lug 52 and causing it to displace the valve 39 from itsseat 40.

The operation of the apparatus is as follows: When it is desired todispense oil or any other liquid from a particular compartment 16, thecylinder 21 is rotated until the indicator 42 coincides with thecorresponding graduation 41, thus indicating that the port 38 is in-registration with the corresponding port 37. By rocking the lever 32,the piston 31 isreciprocated within the cylinder 21 and under the actionof the valves 43 and head- 39 and 46 oil is drawn into the lower part ofthe cylinder on each upstroke of the piston and simultaneously dispelledthere-fromfecting communication between the lower end of the cylinder 21and the corresponding pipe 20 through the ports 38 and 37. Thisobviously allows the oil above and below the piston 31 to drain into thepipe 20 and ultimately into the corresponding compartment. vReferring toFigure 4, I have here shown a modified means for rotatively sustainingthe head 22 upon the head H. In this embodiment of my invention, thehead designated at 22a is provided with a tapered extension 54 whichfits in a. correspondingly shaped socket 55 in the head H. Both of theheads 22a and H are relatively attenuated with respect to the heads 22and H, the extension' 54 serving to rotatively sustain the heads and,consequently, the entire pump upon the tank. The head and the extensionare both formed with a duct 56 adapted to communicate at its lower end'-with any one of a plurality of ducts 57. A pipe 58 c ommunicates witheach of the ducts 57 and this pipe is designed as an extension of thepipe 20 to provide means for conveying oil from the correspondingcompartment to the head H. From the foregoing construction, it will beclear that by rotational movement of the head 22*l any duct 57 canoccupy a communieating position with respect tothe duct 56, so that withthe upper end of the latter provided with a valve 39 as in Figure 2operation of the pump will effect the withdrawal of the oil from thecorresponding compartment into the cylinder of the pump.

Although I have herein shown andv described only Qne form of liquiddispensing apparatus embodying my invention, it is to be understood thatvarious changes and modifications may be made herein without departingfrom the spirit of the invention and the scope and spirit of theappended claims.
